They call it Epimediums, like I'm gonna remember that.
I like Barrenwort or Bishop's Hat.
This plant is said to like shade but barely stayed alive in part shade.Moving it years ago where it gets 3 hours full sun has cause it to multiply 10 fold.
It is native to deciduous woodland areas of Japan, Korea and Manchuria. Love the tiny flowers in the spring and the foliage lasts well into winter.
Oh, the little things that make you happy.
